Cabin Altitude (1,000 ft.) 10 3. The fuselage of a large commercial airliner is approximated as a thin walled cylinder with closed ends. The nominal diameter of the fuselage is 150 inches and the skin thickness is 0.06 inches. The service altitude of the aircraft is 32,000 ft and it is desirable to have cabin pressure corresponding to an altitude of 6000 ft. Using the pressure differential nomogram from Niu (see figure below), obtain an estimate of the hoop and longitudinal stresses in the fuselage skin due to the pressurization loading. Ignore the effects of longerons, frames, etc. (10 points) 16 12 (Example 1) 36 (Example 2) 28 Aircraft Altitude (1,000 ft.) 0 At sea level Fig. 3.8.1 Cabin Pressure Differential Nomogram Pressure Differential (psi) Cabin Altitude (1,000 ft.) 10 3.
